Lowers Cholesterol

  • In 2000 The American Journal of Clinical Nutrition published a published a meta-analysis of 8 studies involving 656 subjects which showed that, when combined with a low-fat diet, 10.2 grams of psyllium per day can lower total cholesterol by 4 percent and LDL cholesterol by 7 percent, in individuals with high cholesterol.

  • In 2005 Archives of Internal Medicine published a 12-week, placebo-controlled study involving 68 patients which showed that 15 grams of psyllium combined with 10 mg of the cholesterol lowering drug, simvastatin was as effective as 20 mg of simvastatin alone in lowering cholesterol. [Source]
  • In 2008 Phytomedicine published a study which showed that after 3 weeks, 3.5 grams of psyllium husk taken 3 times daily significantly lowered total and LDL cholesterol in 54 individuals with hypercholesterolemia. [Source]
  • In 2012 the Public Library of Science published a placebo-controlled study in which 45 subjects saw improvements in cholesterol levels after taking 6 grams of psyllium per day for 6 weeks. [Source]
  • In 2008 Nutrition published an animal study which showed that a high fiber diet containing psyllium husk reduced cholesterol levels in mice. [Source]
  • In 2000 The American Journal of Clinical Nutrition published a study in which men and women with high cholesterol were assigned to either a placebo or 5 grams of psyllium twice daily. After 24-26 weeks LDL cholesterol was 6.7 percent lower and total cholesterol was 4.7 percent lower in the psyllium group. [Source]
  • In 2015 The British Journal of Nutrition published a double-blind, placebo-controlled trial which included 51 adolescents 6-19 years of age with elevated cholesterol levels. Compared to a those participants who took a placebo, individuals given 7 grams of psyllium per day saw a 7.7 percent decline in total cholesterol and a 10.7 percent percent decline in LDL cholesterol after 8 weeks.

Type 2 Diabetes

  • In 2015 The American Journal of Clinical Nutrition published a meta-analysis of 35 clinical trials examining the effect of psyllium on fasting blood sugar levels. The data showed that psyllium had the greatest effect on individuals with type 2 diabetes, with a modest benefit on pre-diabetic individuals. [Source]
  • In 2002 the European Journal of Clinical Nutrition published a study which found psyllium husk to be beneficial in the metabolic control of type 2 diabetics as well as lowering the risk of heart disease without affecting vitamin A and E absorption. [Source]
  • In 2005 the Journal of Ethnopharmacology published an 8-week, double-blind study which showed that 5.1 grams of psyllium taken twice daily significantly reduced the ratio of LDL to HDL cholesterol and improved glycemic control in type 2 diabetics. [Source]
  • In 2016 Nutrition Journal published a controlled study which showed that 8 weeks of 10.5 grams/day of psyllium husk was able to reduce fasting blood sugar, A1C and insulin levels and reduce body weight in 20 type 2 diabetics. [Source]


  • In 2007 Clinical and Experimental Hypertension published a 6-month, open-label clinical trail involving 141 subjects which showed that 3.5 grams of psyllium fiber taken twice daily before meals significantly reduced systolic and diastolic blood pressure and triglycerides in overweight, hypertensive individuals.

Metabolic Syndrome

  • In 2011 The British Journal of Nutrition published a study which compared the effects of fiber from a healthy diet compared to a healthy diet supplemented with psyllium husk. The results showed that both psyllium and a healthy, high-fiber diet improved cholesterol levels and reduced body weight, though the greatest benefit was seen by combining the two. [Source]

Decreased Hunger

  • In 2016 Appetite published a double-blind, placebo-controlled, crossover study which showed that between 3.4 – 10.2 grams of psyllium taken in two doses before meals significantly decreased hunger and the desire to eat. [Source]


  • In 2016 Clinical Gastroenterology and Hepatology published a double-blind, placebo-controlled trial in which 37 children with IBS saw a reduction in abdominal pain episodes after consuming psyllium husk for a 6 week period. [Source]


  • In 2009 the European Journal of Clinical Nutrition published a 40-patients study which found that 2 months supplementation with psyllium husk produced a significant drop in triglyceride levels of type 2 diabetic patients when compared to a controlled group. [Source]
  • In 2008 The British Journal of Nutrition published a crossover study which suggested that an acute dose of psyllium (15 grams) decreased arterial exposure to triglycerides in 10 overweight men. [Source]
